Furthermore, the end composed of the coil and the iron core is wrapped in the soft wrapping body, the soft wrapping body has elasticity, the inlet end of the soft wrapping body is provided with a tightening opening, and the tightening opening is tightened on the traction cable to form sealing fit.

Furthermore, the soft inclusion body is made of a silica gel material.

Furthermore, an elastic guide wire is inserted into the suction pipe, and the elastic guide wire enables the suction pipe to keep an elastic form.

The invention has the technical effects that:

1. this supplementary suction device of gastroscope inspection can enter into the stomach chamber through the alimentary canal entry that is different from the gastroscope entering, and adopt moving mechanism to remove the end of suction tube to the position that needs the suction, often also be the region that semifluid material object such as clot and food residue concentrated, because of it does not get into the stomach chamber with gastroscope pipe entry from same passageway, consequently conditional adoption bore bigger suction tube, can high-efficient suction massive semifluid material, can easily discharge semifluid material object suction when it starts suction device, observe and leave clear clean space for the gastroscope.

2. The moving mechanism is a magnetic suction head arranged at the front end of the traction cable and a magnetic suction part on the traction head, and the magnetic suction head can be moved through a button at the outer end of the gastroscope tube, so that the moving mechanism can be easily attracted with the magnetic suction part on the traction head, and the difficulty of moving the traction head by the moving mechanism can be reduced.

3. For the object that can be inhaled by magnetism when magnetism portion of inhaling, magnetism portion of inhaling self does not possess magnetism, like iron, it includes electrically conductive inner core and insulating skin to pull the cable, it is electrically conductive with the coil to pull the cable front end and be connected, and the coil includes electrically conductive inner core and insulating skin, the coil winding forms the winding on the iron core, it is connected with the power to pull the cable outer end, makes the iron core form magnetic force through switch on, and then the iron core does not form magnetic force during the deenergization to can be through the demagnetization disconnection after magnetic attraction portion of inhaling and removing the traction head, take place to obstruct when avoiding withdrawing from the stomach chamber, also avoid breaking away from greatly dragging in order to make magnetic attraction and magnetic attraction portion break away from the stomach that leads to, and then avoid because of dragging.
